the middle projectbig lightly over the head ; base truncate ; an 

 elongate triangular impression in front of each basal angle, a less 

 distinct impression near each anterior angle (these impressions 

 not meeting); median line well-marked only on disc; granules 

 closely-set, separate, unequal, depressed, unisetigerous, obsolete 

 on sides near cox;e. Elytra heavy, not wider than prothorax 

 (15-5 X 8 mm.), rounded on sides, widest rather behind the 

 middle, transversely convex ; disc light y convex longitudinally; 

 posterior declivity rather strongly declivous ; base broad, roundly 

 emarginate ; shoulder projecting in a strong obtuse prominence; 

 apex widely rounded, without sinuosity or projection near suture, 

 the edge very thick and prominent on each side ; six rows of 

 tubercles on each elytron : first very short, oblique, only notice- 

 able near scutellum : second, fourth, and sixth rows not extend- 

 ing to base or apex : second consisting of eleven or twelve 

 separately, but not widely-placed, small round tubercles : fourth of 

 eight similar tubercles, not extending on to posterior declivity : 

 sixth of much more closely placed stronger and more conical 

 tubercles (sixteen or seventeen), extending nearer to both base 

 and apex than those of second and fourth rows : third and fifth 

 (humeral row) consisting of closely-placed tubercles (twenty-one 

 to twenty-six in a row) extending from base to near apex ; the 

 tubercles more prominent behind, conical on posterior declivity ; 

 a row of fiiie black setse between each row of tubercles. Ventral 

 segments rather strongly impressed on each side of median vitta ; 

 a strong, narrow, oblique impression between first and second 

 segments ; apical segment not as long as two preceding ones 

 together, and having the impression on each side of the median 

 vitta deep, narrow, and parallel. Legs moderate ; femora sub- 

 granulate, cylindrical ; anterior dilatate in middle, arcuate on 

 upper-side, lower-side with a long, narrow, straight, cicatrix-liko 

 ridge on anterior two-thirds ; tibia? rather strong ; four posterior 

 ones with a few short spines on inner side ; anterior with two or 

 three widely-placed dentiform tubercles on lower-side, apex bent 

 broadly inwards, the anterior part of the projection prominent 

 and acute. 



Length, 24 ; breadth, S aum. 



Female. — Differs from the male in the much less dilatate 

 and less convex prothorax (7 '25 x 8 '25), the granules larger and 

 more prominent, the lateral impression of the disc continuous 

 from base to apex, the spaces between the tubercles filled with 

 scales. The elytra broader (16'25 x 10 mm.), more rounded on 

 the sides, posterior declivity a little more abrupt, the apical 

 margin with a small triangular sutural emargination ; the 

 tubercles larger and less prominent, the second and fourth rows 

 with fewer tubercles (only four widely placed ones in the fourth)
